VRB series is one of FHT helical gear precision planetary gearboxes,it is with high precision,and the backlash can be to 2 arcmin.VRB planetary reducer planet gear is supported by both ends of the full needle roller bearing, which enhances the torsion stiffness.Output shaft of VRB planetary gearbox reducer is supported by two taper rollers on both ends to achieve greater bearing capacity.
VRB planetary gearbox is a direct connection type with round body.It is with shaft output,and the output flange is square.The Self aligning input flange makes VRB planetary gearbox connect fast with any motor output shaft.
VRB planetary gearbox reducer has a large range of speed ratio,it has single stage and double stage.Single stage ratio:3,4,5,6,7,8,9,10 ;Double stage:15,20,25,30,35,40,45,50,60,70,80,90,100.
AS a helical gear reducer,VRB planetary gearbox is widely used in all kinds of transmission fields,such as CNC bending machines,machine tools,printing machines,manipulator arm,automobile making,etc.
(1)Quiet operation
Helical gears contribute to reduce vibration and noise
(2)High precision
Standard backlash is arc-min,ideal for precision control
(3)High rigidity&torque
High rigidity&high torque were achieved by uncaged needle roller bearings
(4)Adapter-bushing connection
Can be attached to any motor all over the world
(5)No grease leakage
Perfect solution using high viscosity anti-separation grease.
(6)Maintenance-free
No need to replace the grease for the life of the unit.Can be attached in any position.
